Just saw Bauer’s live press conference at 12:10 pm EDT on only one cable channel (Headline News), as the news of Senator Kennedy’s passing dominates most outlets, although MSBNC did just mention it as “breaking news”:

COLUMBIA, S.C. – South Carolina’s lieutenant governor will ask embattled Gov. Mark Sanford to resign at a news conference Wednesday, a spokesman said.

Lt. Gov. Andre Bauer will agree to stay out of next year’s governor’s race if Sanford steps down, an offer he first made in June after his fellow Republican admitted a yearlong affair with an Argentine woman.

“People need to take their personal, political considerations off the table and think about what’s best for the state,” Bauer spokesman Frank Adams said.

Sanford has previously said he has no plans to resign. His spokesman did not immediately return a call Wednesday.
